Apps may change the window hierarchy while recursing over it by
destroying windows from the expose event handler. We need to copy
the children list and ref all the children while recursing.
This fixes some crashers in gedit (bug #589367, bug #591434)
The X11 queue_translation operation uses NextRequest to get the serial
of the XCopyArea operation where the translation should end. However,
if the gc passed to gdk_draw_drawable has a non-flushed clip region
(which it commonly has now for the window clipping) then the next
operation will be the GC flush, not the XCopyArea.
To handle this right we now pass in the GC to be used to
queue_translation and ensure that it is flushed before calling
NextRequest().
When we copy the region we need to also re-expose the areas of
the copied region that was not also in the destination.
And, we need to do this invalidation after the move, as the
move also moves any invalid area.
If there are outstanding moves in an area that intersects
the source of an outstanding move we need to move the invalid
area correspondingly, otherwise we will expose the wrong area
as the outstanding move copy will happen before we expose
the invalid area.
When moving an area we move any invalid region in this area to the
new place, but there really is no need to remove the old invalid
area as it would just be invalidated again (being newly exposed).
Previously, this flag wasn't cleared properly when the notebook lost
focus, but only when the notebook was focussed again later.
As this flag is only used to advance correctly focus pages by grabbing
focus to the new page after switching the page, this is not good.
In particular, it can cause a focus grab when programmatically switching
the notebook page and the focus is inside a completely different widget.
A previous attempt at this fix in
6e0af6c252 has been reverted in
dfe0c8c0ca because it didn't work
correctly.
This extends the usage of the native clear region call such that its
called also for windows that have parent relative background all the
way up to a native window. That way we get true background relative
background clearing even to a foreign parent, which means that some
transparent notification icons look right again.
GdkDrawable->draw_drawback was replaced with a new vfunc
draw_drawback_with_src that is now called from gdk_draw_drawable.
However, some code seems to call the vfunc directly (see bug #591288),
so make it chain to the new call.
Note that such direct vfunc calls are a bad idea and won't work for all
cases.
This moves the native show/hide calls to the generic code
for calculating viewable rather than in its own separate code
called from gdk_window_show/hide. This simplifies the code a bit,
but most significantly it means things are correctly shown when
they become viewable for other reasons than a show/hide call.
For instance, this fixes bug 590442 (gvim embedding) where the
toplevel GtkPlug is mapped by the embedder and we didn't previously
pick up that the native children became viewable and should be shown.
Print when Enter pressed in Name entry or Command Line entry in the
print dialog (#564695).
Add gtk_printer_option_set_activates_default() function and
gtk_printer_option_get_activates_default() function to control
behaviour of GtkPrinterOptionWidget.
We used to invalidate the whole window when raised, but this is
unnecessary much, we now just invalidate the visible area minus the
previously visible area.
This also fixes a problem where expose calling raise caused a loop (#588438)
This never worked before csw since the root window is never
set as IS_MAPPED, but with the new viewable check (which is
true for the root window) we could erronously queue exposes
on the root window.
This happened unexpectedly in bug 589369, where metacity
got a GraphicsExpose event on the root window due to some
graphics operation, queueing an expose which would be handled
by clearing that area. That is fixed with this commit.
When printing, increment page sequence before rendering of the page,
not after (#590084).
In opposite case it runs "end_page" function with wrong parameters when
drawing a page in another thread.
